Dynamic Electro-thermal Simulation Software for Power Devices

STMicroelectronics‘ ST PowerStudio is a dynamic electro-thermal simulation software dedicated to power devices by ST. The software provides a comprehensive power and thermal analysis able to predict the device performance, shortening the solution design and saving time and resources. Furthermore, the tool helps to select the proper device fitting the application mission profile.

ST PowerStudio is based on a very precise built-in electrical and thermal model, for each device, and thanks to an iterative calculation, taking into account the self-heating effects, it provides a highly accurate estimation of the power loss and the junction and case temperatures.

The software is able to simulate mission profile with static load (single set of input conditions) or a dynamic load, changing the input conditions over the time and performing very long simulation profile.

Simulation results are shown on tables and on dedicated scope views, as function of the time, the load current and switching frequency. An output report is provided with the summary of all the information and results for an easy comparison or archiving.

Several thermal set-up input conditions can be simulated, such as:

devices without heatsink, estimating the case and the junction temperatures;
